ACCESS POINT DEVICE AND MONITORING SYSTEM USING THE ACCESS POINT DEVICE
A monitoring system includes at least one network camera distributed in an area to be monitored, an access point device connected with the at least one network camera. The access point device includes ports, micro control units, and a central processing unit. Each micro control unit is connected to one of the ports, and the central processing unit is connected with the micro control units. The central processing unit assigns an IP pool to each micro control unit and receives captured images from the ports. Each micro control unit assigns an IP address from the IP pool to a corresponding network camera, and manages the captured images according to the IP addresses.

1. Technical Field
Embodiments of the present disclosure generally relate to monitoring technologies, and more particularly to an access point device and a monitoring system using the access point device.
2. Description of Related Art
Network cameras are commonly used in a monitoring system. When there are many network cameras used, each of the network cameras may be assigned an Internet protocol (IP) address for distinguishing them apart. As shown in
What is needed, therefore, is an improved monitoring system to overcome the limitations described.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
In one embodiment, the switch 24 includes a first port 240a, a second port 240b, and a third port 240c. The first port 240a is connected with the processor 23, and for receiving the processed images. The second port 240b is an extension port of the network camera 2 for connecting to an external device such as another network camera 1, which allows the connection of many network cameras 1 or other devices in series. The third port 240c is connected to a monitoring device 3, and transmits the processed images to the monitoring device 3. In other embodiments, the switch 24 may have more than one second port 240b, for extending the functions of the network camera 2. The monitoring device 3 may be a personal computer, a mobile phone, or a personal digital assistant, for example.
In one embodiment, the first port 240a can be a medium independent interface port or a reduced medium independent interface (MII/RMII) port. The switch 24 can be an ethernet switch. The switch 24 and the processor 23 are connected in series by the MII/RMII port. As illustrated in
In
For example, if the network cameras “2a,” “2b,” “2c,” and “2d” distributed in an area “A” are connected to the port 12a of the AP device 2, and the port 12a is connected to the MCU 11a, the CPU 10 distributes the IP pool “192.168.2.1˜192.168.2.255” to the MCU 11a. The MCU 11a assigns an IP address from the IP pool “192.168.2.1˜192.168.2.255” to each of the network cameras 2a-2d, and manages the images captured by each of the network cameras 2a-2d according to the IP addresses. The captured images of the network cameras 2a-2d can be transmitted from the AP device 1 to the monitoring device 3 for monitoring via the network cables 4.
Although certain embodiments of the present disclosure have been specifically described, the present disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the present disclosure without departing from the scope and spirit of the present disclosure.
